BS PD CLC/TS 50661-1:2017 specifies the requirements for security systems to provide detection of intruders in external areas outside enclosed buildings.

For enclosed buildings EN 50131-1 should be applied. CLC/TS 50661-1 may be used for unenclosed buildings such as roofed storage areas where an intruder and hold-up alarm system is not suitable.

This Technical Specification specifies performance requirements for installed EPSS but does not include requirements for designing, planning, installation, operation or maintenance.

These requirements also apply to EPSS sharing means of detection, interconnection, control, communication and power supplies with other applications.

This Technical Specification references requirements for system components according to the environment where they are expected to operate as designed. These environmental conditions are classified.

This Technical Specification does not deal with requirements for compliance with EC regulatory Directives, such as the RED Directive, EMC Directive, Low Voltage Directive, etc. except that it specifies the equipment operating conditions for EMC susceptibility testing as required by EN 50130-4.
